Read Ottawa's plans for residential window energy efficiency

The document "Market transformation strategies for energy-using equipment in the building sector" lays out a plan formulated at the Energy and Mines Ministers Conference in New Brunswick in August to make Canadian buildings much more energy efficient. It's part of the overall plan to meet Canada's obligations under the Paris Climate Accords to reduce greenhouse gas emissions, and it's the plan that Debbie Scharf of the National Research Council has been talking about to industry groups all over the country this years. One section of the plan directly addresses residential windows and outlines an "aspirational" goal to encourage the use of the best technology in windows and reduce emissions from home heating by nine percent across the country.
